HOG OILER.

Application filed `:rune 26, 41.925. serial No. 39,648.

To all who/nt t muy conce-7%.'

Be it known that we, THOMAS E. PECK and F RANK lV. HARRISON, citizens of the United States, land residents of Sioux City, in the county of foodbury and State of Iowa, have invented certain new and useful Improvements in a Hog Oiler, of which the following is a specilication. v

Our invention relates to a hog oiler, and has for its object primarily to provide an oiler which will spray the backs of` hogs passing through 'a gateway forming a part of the invention.

vMore particularly, our invention `is em.- bodied in a structure in which a nozzle for spraying oil depends from the top ot a gateway, in which is hinged at its 'Lipper edge a gate, adapted to actuate Aby its Swinging, a valve which controls the flow of oil to the nozzle, and a pump being provided to force the oil under pressure from a suitable tank through the valve and to the nozzle.l

Another object is to provide Such a structure in which a pair of nozzles may be used, one located on either side of the gate, together with a two-way valve, so actuated by the swinging of the gate thatwhen the gate ,is depending the valve will be closed, and when the gate is swung to either Side the valve will open the pipe line to the nozzle on the other Side of the gate.

Another obj ect is to provide such a structure having ja frame supporting the oilspraying mechanism, and which is adapted to be readily inserted in van opening provided 'or it in a hog fence.

With these and other objectsin View our invention consists in the construction, a1'- rangement and combination of the various parts of our device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which:

Most of the hog Aoilers which have been devised aim todistribute oil to the side ot a hog by rubbing contact of the hog with a suitably disposed rotating drum mounted in somemanner to'receive oil at its periphery. Such devices usually are not e'lcient in distributing oilv to the back of the hog, where it is most needed, and the present invention contemplates spraying the oil on the back of ahog vfrom, whence it will work its way onto the sides.

kThe oiler has a gateway frame, 10, of angle ,iron, which is adapted to beA inserted in a suitable gateway of wooden Studdingy or the like, formed for the purpose in .a hog fence, as indicatedin dotted lines at 11, in Fig. 3. In bearings, 12 and 13,: secured to the frame, 10, is mounted a horizontal shaft, 14, which-extends'. at one end through the side of they frame, 10, in-,order to receive vthe actuating mechanism, which wwill be later described-herein.

A gate, 15, which may be of sheet metal or woodis secured by means-of yokes, or

the like,'16, to the Shaft, 14, so that swinging of the gate will cause the shaftto oscillate. l An oiltank, 17, may be supported in any suitable position `from the gateway, as by bra ckets,18, securing itto the upper side thereof. Y 'i `A pump cylinder, 19, is Supported by 'i means of brackets, 20, on the side of the iframe, 10, and a'tube, 21, connects the upper end of said cylinder to the tank, 17. A check valve, 22,1 of ordinary construction is inserted between the tube, 21, and the pump cylinder, 19, so as to check the flow of.

oil fromv the-pump cylinderl back tol the tank, 17, and to allow flow of oil from the tank, 17, to the pump cylinder.

' A Short tube, 23, communicating with the upper end of the pump cylinder through the medium of a similar check valve, 24, communicates with. andvserves to support a two- Y way valve, 25. The valve, 25, has the entranceway, 26, and the two eXit passages, 27 and 28, respectively. ,n n The tube, 23, 'is thread-ed into ,the passage,

26, andthe tubes, 31 and 32,y Yare threaded into vthe*passages, 27 and 28, respectively.

The discharge tubes, 31 and'32,A are eXtended upwardly, as at 83, to a plane just above the shaft, 14, and are'thence bent laterally and crossed, as at 84, in the space above theV door, 15, and below the frame, 10.

At the point where the tubes, 31 andi 32, cross, they are suspended by a bracket, 35, in the frame, 10. T lie-ends ofthe tubes are bent'downwardly as at 36 on either side of the gate, 15, andare provided with nozzles, 87 and 37a.

The valve, 2V, is adapted to establish communication between the tubes, 23 and 31, or and 32, when the gate, 15, is swung in either direction in order that oil may be ,lelivered to the proper nozzle, 3'. For this purpose we provide a valve-actuating means as follows.

'l""l1e.bearing, 13, is formed as part of a bracket, having an ear, 38, by means of which theV bracket .is secured to the frame side member, 10,v and having an arm, 39, bent outwardly parallel to the shaft, 14, and vspaced thereunder. The end ofthe arm, 39, is provided with a bearing, 40, .in which is journaled the spindle, 41, of4 a pinion, 42". The pinion, 42, and spindle, 41, areformed integrally, and to thelower. end ofthe spindle, 41, is securedy a socket, 43, having a squaredopeningwhich receives the squared shank, 44, of the valve core, 29.

rihe core,r29,' extends vertically through the valve casing at the juncture between the three. passages, 26, 27 and 28, so as to separate'them. The core, 29, has an arcuate cavity, 80, which is off'such Width that when the coreV is neutral position', las shown Yin Fig.y 4, 'the' passages, 27 and 28, will'be' entirely closed by the remainder of the valve core, the opening, 30, being positioned registering with. the passage, 26.

The movement of the valve core, 29, through an are of 45 degrees to 4either side `of neutral position showninFig.A 4, will establish communication between the passage, 26. and one ofthepassages, 27:011 28, the other passages remaining closed. These two positions of the valve core are indicated in dotted lines in Fig. 4.

Before proceeding further, it may be stated Vgenerally that the mechanism is so "an'ged that the. valve, 25, will'open'rapidly when thegate, 15, commences to swing in either direction and thereafter when the valve has already established communication between theproper channels, .oil will be pumped from the cylinder, 19, through the discharge channel, which has been opened. ln Order that'the valve may be opened rapidly and maintained ineither of its full open posit-ions illustratedv in Fig. .4in dotted lines, we provide the following mechanism.

i VThe pinion, 42, has an upper conical`face, 45. in which are cut two gear teeth, 46, and a lower. cylindrical face, 47, which is cut cylinder, 19.

away to form a wedge-shaped nose, 48, positioned directly below the teeth, 46.

To the shaft, 14, is secured a gear comprising a disk, 49, having an annular plane rim, 50, and three crown gear teeth, 51, formed adjacent and within the rim, 50. A depression, 52, is formed adjacent the teeth, 51, in the rim, 50, and receives the wedge-shaped nose, 48, of the pinion, 42. The teeth, 46, mesh with the crown teeth, 51, of the'gear, and the flattened side faces, 53,' are adapted to slide against the rim, 50,

ofthe rim after the gea-r has rotated to a position where the teeth, 46 and 51, no longer mesh.

The gear visvof such size that upon swinging of the gate 15, and result-ing oscillation ofthe shaft, 14, the rotation of the gear will rapidly revolve the pinion, 42, to a position where the valve, 25, will be open, and thence the fiat face, 53, which is in cont-act with the rim, 50, will lock thel pinion in the correct-position to maintain the valve in full open position. l/Vhen the gate is-in verticaldepending position, thegear teeth, 51, will beV in the bottom ofthe gear and the nose,-48,' of the pinion will be received within'the depression, 52, ofthe gear.`

`The operation of the pump is designed to vproceed at a rate varying inversely to that of the operation of the valve. That is, its

'piston commences to move slowly and thereafter moves more rapidly. In order to 'effect this, we provide a crank arm, 54, se- 'l cured to the outer end of the shaft, 14'. A piston, 55, is carried on the inner endof a piston rod, 56, slidably extended through a packing gland, 57, in the end of the pump hingedlysecured tothe crank arm, 54, Vand piston rod, .56', so that as the crank arm, 54, moves in an arc withV the oscillation offthe shaft, 14, the connecting'rod, 58, will move up fand down with a harmonic motion, and correspondingly move. the piston, 55, comit moves upwardly.

The check valve, 24, allowsowV of the oil from the' pump cylinder,l 1 9, te the valve, 25, and checks the How of oil in a reverse direction.

It will now be seen that as a hog proceeds through the gateway in the direction indi'- cated'by the arrow, 59, in Fig. 2, and swings the gate in that direction, the gear, 49, will be rotated as indicated bythe arrow, 60, `in Fig. 2,' and the pinion, 42, will'be rotatedfas indicated by the arrow, 61, in Fig. Gorrespondingly the valve core, 29, will be rotated as indicated by the arrow, 62, in Fig. 4,"andth'e cavity, 30, will be brought to the dotted: line positions indicated the inencinn' slowly and increasing 1n speed as A connecting rod, 58, isl'o5 arrow, 63, in Fig. 4. Communication will4 y then be established between the tubes, 23

Lacasse;

- depends over the gateway on that side ofthe gate 'from which the hog is proceeding.

rihe parts are so arranged that the spray of oil will commence when the shoulders of the hog are directly under the nozzle, 87, and continue until the oil has been distributed along the majority of the length of the hogs spine. then the hog moves in the 4other direction the nozzle, 37, will act.

As the pump piston, 55, moves downwardly with the return swing ot the gate, oil will be drawn in through the tube, 21, from the tank. .17. l

The crank arm, 54., is secured in the shalt, 14, by threaded nuts, 54, by adjustment ot which the throw of the arm may be lengthened or shortened. The stroke of the piston in the cylinder may thus be varied. lVhen so' adjusting, the length of the cylinder will allow the added movement of the piston caused by t-he lengthening ci' the crank arm.

In order to check the swing of the gate beyond center on its return swing, we'provide a U-shape'd keeper, 65, which is pivoted to the frame by means of a bolt, 66.I A coil spring, 67, serves to impose tension on the bolt, 66, and thence upon the keeper. The coil spring is received over the bolt and when the oiler is installed in a gateway of a fence, the spring will be compressed between the outer end of the bolt and the outer tace of the joist, 11. A hole may be bored in the joist to receive the bolt. slot is provided in the joist on the other side of the gateway to receive the shaft, 14.

The lug, 68, secured to the gate, 15, is so positioned as to normally be received be tween the arms of the keeper, 65. As the gate swings in one direction the keeper will be tilted to that side, remaining there to vreceive the lug as the gate swin gs back to center.

Some changes may be made in the construction and arrangement of the parts of oury invention without departing from the real spirit and purpose of our invention, and it is our intentionto cover by our claims any modified forms of structure or use of mechanical equivalents which may be rea-r sonably included within their scope.
